  <p>Generates a RNG version 4 UUID as a <a href="../../uuid_value/UuidValue-class.html">UuidValue</a> object</p>
<p>By default it will generate a string based mathRNG, and will return
a <a href="../../uuid_value/UuidValue-class.html">UuidValue</a> object. If you wish to use crypto-strong RNG, pass in UuidUtil.cryptoRNG</p>
<p>The first argument is an options map that takes various configuration
options detailed in the readme. This is going to be eventually deprecated.</p>
<p>The second argument is a <a href="../../data/V4Options-class.html">V4Options</a> object that takes the same options as
the options map. This is the preferred way to pass options.</p>
